C1q neutralization during epileptogenesis attenuates complement‐mediated synaptic elimination and epileptiform activity

open access: yesEpilepsia, EarlyView.
Abstract Objective Accumulating evidence indicates that aberrant C1q‐C3 complement signaling in microglia and astrocytes drives synaptic dysfunction and neuronal loss. C1q‐mediated synaptic dysfunction disrupts neuronal circuitry balance and can lead to network hyperexcitability in epilepsy.

Is sleep affected after microgravity and hypergravity exposure? A pilot study

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep is known to be affected in space travel and in residents of the international space station. But little is known about the direct effects of gravity changes on sleep, if other factors, such as sleep conditions, are kept constant. Here, as a first exploration, we investigated sleep before and after exposure to short bouts of microgravity ...

Pharmacological manipulation of L-carnitine transport into L6 cells with stable overexpression of human OCTN2 [PDF]

open access: yes, 2018
.: The high-affinity Na+-dependent carnitine transporter OCTN2 (SLC22A5) has a high renal expression and reabsorbs most filtered carnitine. To gain more insight into substrate specificity of OCTN2, we overexpressed hOCTN2 in L6 cells and characterized ...

Cognitive-enhancing effect of Cordia dichotoma fruit on scopolamine-induced cognitive impairment in rats: metabolite profiling, in vivo, and in silico investigations

open access: yesRSC Advances
Many plants are reported to enhance cognition in amnesic-animal models. The metabolite profile of Cordia dichotoma fruit methanolic extract (CDFME) was characterized by LC-QTOF-MS/MS, and its total phenolics content (TPC) and total flavonoids content ...

Role of Endoscopic Ultrasound‐guided Gastroenterostomy for Benign Gastric Outlet Obstruction

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Benign gastric outlet obstruction (GOO) often results from intrinsic conditions like peptic strictures, caustic‐induced stricture, and surgical anastomoses, and extrinsic conditions like pancreatitis, hematoma, and superior mesenteric artery syndrome.
